IMPROVEMENT IN ROOT AND STUMP PULLERS.

Specification forming part of Letters Patent No. 213,473, dated March 18, 1879; application filed January 11, 1879.

To all whom it may concern:

Be it known that I, JoHN G. TRUMP, of Denmark, in the county of Tuscola and State of Michigan, have invented a new and valuable Improvement in Root and Stump Pullers; and I do hereby declare that the following is a full, clear, and exact description of the 0011- struction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a perspective of my root and stump puller, and Fig. 2 is a detail view of the chain with hook attached.

My invention relates to a device for pulling stumps, roots, and the like; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth.

In carrying out my invention, I employ a properly-braced tripod, each foot of which is supported on runner-shoes, the beveled portions of which all point in the same direction, the forward foot being provided with a clevis, or other suitable means for connecting with a draft power, for convenient transportation. The forward leg is bolted between the two rear legs, and a bolt passing through said rear legs near the top carries a loose pulley in the center, upon each side of which depends a chain.

The stump-chain operates over the loose pulley, and the drop-chains are of differential lengths, each having at the lower extremities a clevis, connected to a hand-lever having a jaw-clutch upon the inner end.

It will thus be observed that by my construction one of the hand-levers hangs lower than the other, and consequently the jaws clamp the stump-chain and manipulate the same below the corresponding operation of the other.

The stump-chain has hooks upon each end, one of which has an upwardly-extending arm, which is adapted to clamp roots and the like between itself and the chain.

Referring to the drawings, A represents the forward, and A A the rear, legs of the tripod, bolted together at or, having suitable braces 64, and each leg being provided with runnershoes B, having beveled lower surfaces, 6, in one direction, as shown. A clevis, 1), allows draft attachment for transportation of the device.

0 represents a bolt, passing through the legs A, carrying a loose pulley, C, over which operates the stump-chain D, having hooks at each end, one of which, at, has an upwardlyprojecting arm, d, as shown.

Depending from the bolt 0 is a short chain, E, from one side of the pulley, and a long chain, E, from the opposite side. The lower end of each chain is provided with a clevis, F, the connecting-bolt of which acts as the fulcrum of levers G, having jaws H upon their inner ends, which engage the stump-chain, as is obvious, one operating above the other upon the chain.

I claim 1. The combination of the bolt G, pulley O, stump-chain D, long and short chains E E, clevis F, and lever G H, as and for the purpose specified.

2. The stump-chain D, provided with the root-hook 01, having arm d, as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN G. TRUMP.
